The Device Automation Bus (DAB) protocol is developed as a result of collaboration between Amazon.com, Inc, Google LLC and Netflix, Inc.
Device Automation Bus is a simple protocol for intuitively interacting with consumer electronics in the living room that are connected to the Internet such as Smart TVs and gaming consoles. DAB enables device manufacturers and application developers to programmatically start and stop applications, send key presses to the device, restart the device, capture device metrics among other operations. Using DAB, device manufacturers and application developers can automate manual tasks such as application compatibility
checks, cross application performance testing and monitoring device memory usage. Automating manual tasks provides reliable results and saves time and money.
